I did find a way to resolve this problem, however. The computer is a multiboot, with Opensuse 15.0 on a separate partition.
You failed to say that before.
Booting two different Linux on the same disk is not plug and play, you have to do work yourself.
That seems counter-intuitive. I'd have thought that scenario was: - at least as common as dual-boot with e.g. windows, especially among developers/testers
Certainly.
- more fully controllable
It is, manually :-)
- easier to fix in the case of problems
It is and it ain't :-)
So I'm curious if there are reasons why, or if it's just lack of bandwidth?
It just is. It is easier if the machine is UEFI, because UEFI does contemplate multiple bootable systems. But BIOS was designed for a single operating system: to boot "others" hacks had to be designed. LILO, GRUB... Possibilities - the one I prefer: Install generic boot code on MBR (preferably from syslinux) Install each LINUX system with GRUB on the "/" or root partition. Mark the main one as "bootable" in the partition table (classic or GPT). Changing which is the main one is as simple as putting the boot mark on another partition. Each Linux must "probe" for other systems to be able to load the "other". Alternatively, edit manually "/boot/grub2/custom.cfg" to chain load the other grubs. The other method, is to have a system as main, with grub in the MBR. The second system must be told to install Grub into root (and it will complain that it is not bootable). Then probing on the first system will locate the second. Or, edit manually "/boot/grub2/custom.cfg". Notice that letting one system find the other must be repeated each time the kernel in the second system changes. If each system is told to install on MBR, each time grub is updated may take away booting from the other system. This is not tidy. There is no option to tell YaST that you are installing a second Linux. -- Cheers / Saludos, Carlos E. R.
